Uranium crystallization tests using a rotary kiln type crystallizer were carried out in an engineering scale in NEXT process condition. First, a steady state operation test was performed to confirm a stable crystallizer operation. Next, non-steady state simulation test was performed to understand non-steady state phenomena on the crystallizer and to design the measurement system of crystallizer.
